Drip .. Drip .. Drip. If you had a dripping tap at home you'd probably fix it. You may also be surprised to know that many office processes are like that dripping tap. There's a small spurt of action followed by a long wait, followed by another small spurt of action and another long wait, until eventually the end is reached or people lose interest. More often than not, nobody bothers to fix the leaky process. They just accept it as normal.
Whilst the analogy is not perfect, it serves to highlight that 'flow' is not the first thing that comes to mind when most people think about how things get done in their organisation. A process should be either on and doing it's intended job, or off and waiting for the next trigger. Drips cause delays and delays cause waste.
So why not make a commitment to audit your organisation's most used processes for drips and see if you can't get some flow happening. You don't need a plumber. Just a simple value stream map and some measurements should be sufficient to open up the taps.
